The base starts with a plywood frame constructed much like the extension frames: nails or screws, plus glue. Top off the frame by gluing on 1/4-in. plywood (L). Now you’re ready to wrap the frame with solid wood facing using one of my favorite woodworking shortcuts: Instead of routing the facing, then fussing with mitered corners, glue on the facing before you rout and just form simple 90-degree butt joints at corners. Sand the corners flush and then rout the facing (Photo 2). You’ll get tight, perfect corners—fast.
Build this handy stool in one hour and park it in your closet. You can also use it as a step to reach the high shelf. How to make storage shelves: All you need is a 4 x 4-ft. sheet of 3/4-in. plywood, wood glue and a handful of 8d finish nails. Cut the plywood pieces according to the illustration. Spread wood glue on the joints, then nail them together with 8d finish nails. First nail through the sides into the back. Then nail through the top into the sides and back. Finally, mark the location of the two shelves and nail through the sides into the shelves.
